This conical washer-style spring stores elastic energy under compressive load and releases it in a controlled, predictable manner. Manufactured from stainless steel, it is suited for applications requiring corrosion resistance and consistent spring force. At 0.75 inches outer diameter and 0.059 inches overall height, this spring is sized for use with 3\/8-inch bolt assemblies. It provides a rated load of 10,314 pounds at a deflection of 0.0272 inches, making it appropriate for high-load, small-deflection clamping and preload applications.\u003c\/p\u003e\u003cp\u003eBelleville disc springs of this size are commonly used in mechanical assemblies where bolt preload retention, vibration dampening, or thermal expansion compensation is required. They are installed in stacked or single configurations on fastener shanks, valve seats, pressure relief assemblies, and precision clamping fixtures. This part is appropriate for industrial, HVAC mechanical, and trade equipment applications where compact spring geometry is critical. Installation is typically performed by mechanical technicians or machinists working with fastener and bearing assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance for demanding service environments\u003c\/li\u003e\n\u003cli\u003eHigh load rating of 10,314 pounds at 0.0272 inches deflection in a small form factor\u003c\/li\u003e\n\u003cli\u003e0.75 inches outer diameter with 0.38 inches inner diameter for 3\/8-inch bolt fitment\u003c\/li\u003e\n\u003cli\u003e0.059 inches overall height allows stacking for increased deflection or load tuning\u003c\/li\u003e\n\u003cli\u003eConical disc geometry delivers consistent axial preload under compressive force\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/8-inch bolt assemblies.

Ensure all equipment is de-energized or depressurized before servicing any assembly containing disc springs. Springs may be stacked in series to increase deflection or in parallel to increase load capacity; consult the manufacturer load-deflection data before configuring stacks. Do not exceed the rated deflection, as over-compression can cause permanent set or component failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 0.059 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.0272 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 10,314 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MB0750-040-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52014652162354,"sku":"MB0750-040-S","price":24.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/053b45f640540db21b83268cd66adaad.jpg?v=1790007168","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb0750-040-s-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
